LootHunter: Good. And you should also clarify if you mean "have male protagonist" or "have only male protagonist".
dtgreene: Those with only male protagonists vastly outnumber those with only female protagonists.
Of course, there are games where you can choose to play a male or a female character (and rarely, a non-binary character, but that isn't common). With that said, I have seen games where you create your character, but that character has to be male (Eschalon Book 1 comes to mind); I have not, however, seem any games that force you to create a female character.
You know there are games where the PC is a female, and why not.
If they let you create the character, not letting the PC be a female, might be laziness/lack of resources in a very tight budget game as Eschalon is.
Actually, even if a game is interactive and all that, it is providing you with graphics (unless it is a pure text game). Therefore the immersion, while great, falls below what a written story, such as they come in those devices we call books. And literature boasts plenty of female points of view, as well as male.
So why not getting into the skin of people who might be unlike the player or reader is, if the experience will engross the player or, better, will help the reader grow as a person with a few grains of truth told beautifully, condensed from the entrails of the writer and what the writer managed to learn about the world?
